The aggregation of multiple objects is called aggregation. Aggregation objects are container objects that can contain a group of objects. Iterative subpatterns encapsulate iterative logic into a separate subobject, thus separating it from the aggregation itself. Iterative subpatterns simplify the aggregated interface. Each aggregated object can have one or more iterative subobjects, and the iterative states of each iterative subobject can be independent of each other. Iterative algorithms can be independent of aggregation role changes.
